SUMMARY OF THE INVENTION The present invention relates to the light profile of a luminaire and the cooling characteristics of the light emitter, and more particularly to a luminaire having a light emitter of a selectable set position, orientation and number.

A luminaire housing design can be used to set different illuminating components by changing the characteristics of the luminaire instead of changing the luminaire housing, for example, in incandescent and fluorescent luminaires, using the same luminaire housing to vary different illuminating components In some cases, the shape of the light profile is varied by using different wattages or numbers of bulbs, or by including an adjustable reflector and/or shape.

The temperature at which the luminaire controls the light source is important for performance and longevity, especially in recent high-efficiency lighting technologies, such as LEDs, laser diodes or other light emitters, LEDs are usually chosen for reasonable cost. There is maximum illumination output under energy consumption, because the LED source operates at a lower temperature than a typical incandescent source, and less energy is consumed in the form of thermal energy. However, LEDs are more sensitive to operating temperatures and The low operating temperature also provides a small temperature difference between the LED and the external environment, so more attention is required in thermal control to transmit and dissipate any excess heat generated by the LED driver and transmitter, making the design Component The operating temperature will not exceed.

LED luminaires usually include both LED drivers and LED emitters. Most of the operating temperature is for LED emitters. When the temperature rises, the performance of the LEDs decreases, the light output is reduced, and the life of the LEDs may be reduced. The LED emitters are typically of the LED package type, for example, a package comprising one or more LEDs, a fixed substrate such as a ceramic, and an optional lens structure.

In order to promote heat dissipation, convection, conduction and radiation are heat transfer modes. For LED lamps, conduction heat dissipation is usually set to be placed on a heat sink through one or more LED packages. The heat sink is usually integrated with the lamp housing. Or thermally coupled, the luminaire housing typically includes an external cooling fin to further promote thermal energy dissipation through convection and radiation.

In conventional LED luminaires, the heat sink is usually integrated with the luminaire housing so that thermal energy can be more efficiently conducted to the outside of the luminaire housing and is dissipated by thermal convection and thermal radiation. However, in such a design, It is difficult to prevent thermal energy from being transmitted from the LED emitter to the LED driver. Moreover, such an arrangement also limits the design of the single lamp housing, for example, each LED package is directly thermally coupled to the heat sink and the heat sink is used with the lamp housing. An integrated, fixed way that provides the functionality of LED transmitters in different orientations and quantities.

In some conventional LED luminaires, different structural features are used to provide selectable LED orientation and number, however, these features may limit transmission through conduction heat dissipation and/or cause unnecessary complexity and cost.

For example, in order to provide a selectable orientation for the LED package, one prior art design is to mount the LED package by a spring to be placed by the heat sink The extended studs, the height of the springs combined with the studs determine the orientation of the LED package. However, this design requires a heat pipe to connect the LED package to the heat sink. Another prior art design provides several LEDs to be placed in a rotatable On the mount, however, the mount and the rotating mechanism limit the transfer of thermal energy to the outer surface of the luminaire housing from which it can be vented.

Other prior art luminaire designs include a cylindrical heat sink that forms a plurality of flat surfaces around the periphery, each flat surface housing a different LED package that can be based on the particular LED package The choice of LED intensity required for the direction of the orientation. In this prior art, in order to promote the dissipation of thermal energy from the LEDs, the interior of the cylindrical heat sink protrudes inwardly to form a cooling fin, and the cooling structure is arranged to exist in the lamp housing. Allowing the gas to pass through the center of the cylindrical heat sink to open to the outside world. In addition, the same heat sink surface and corresponding bumps are used to house each LED package, regardless of the specific surface of the heat sink and the corresponding bump. The LED package needs to be dissipated with thermal energy.

Accordingly, it would be desirable to provide a luminaire having a single housing that can be provided with a variety of LED structures and that has suitable heat sinks and reflector designs for each LED structure.

The present invention may include one or more of the features described in the appended claims, and/or one or more of the following features and combinations thereof.
